The Internet Archive is a nonprofit digital library that preserves web data and makes it available for research purposes through the Wayback Machine. We began archiving the web in 1996, and currently have preserved over 150 billion web documents.

The Internet Archive partners with universities, libraries and others to preserve the world's cultural heritage. In addition to our web preservation activities, we also provide free access to more than 2 million digital books, more than 600,000 audio items, and more than 300,000 video items. Please visit our News & Announcements forum to read more about our projects.

Webmasters: User Agent archive.org_bot is used for our wide crawl of the web. We try to crawl at a pace slow enough to not disrupt normal web activity. You can learn more in the Wayback Machine FAQs. If you notice archive.org_bot behaving badly, please contact us at

We feel is it imperative to preserve web data for future generations. Unlike print media, web pages can and do disappear into thin air.
